Hey all. I'm looking for some good ideas. I've been running thse bikes for years and know about the coil recall and problems. This symptom is similar, but coils have been replaced twice (despite testing showing they're good) and a new coil harnes has been tested and installed also/anyway. Fuel pump went from semi functional to dead while I'm diagnosing the problem, so that is new too. I've pulled the TPS, tested (okay!), cleaned anyway, reinstalled and adjusted. Plugs are newish. I have two of these bikes and spares, so parts swaps are easy at home or at the track. CDI has been swapped to two others with no change in symptom.
Symptom: At high RPM (12k & 14k) there is power loss. Power returns if I back off slightly from full throttle...like a carburetor. This does not happen when the bike is cold, but seems to get worse when it is hot and into the 3rd session of the day. The symptom is not consistent, making it a challenge to diagnose. It can only be replicated in a track environment, furthering my challenge to properly diagnose and repair it.
Open to good ideas from parts swaps to try, to diagnostic help. Bobblehead? Pit Lane Moto? Bueller?
Would really appreciate the assist. Thanks!
